How to get Current logged in user for UI5 application in SAP Portal

Hi,

I am building an UI5 app and deploying it in SAP Portal.

I need to retrieve User Id of logged in user of SAP Portal who is accessing the UI5 iView . Can you please suggest how to get logged in user details in SAPUI5.

I went through the SCN forms but didnot find an official way of finding the logged in user for UI5 app.

Thanks and Regards,
